In the current era, do any wizards survive from 1372 DR?

The D&D 3e Forgotten Realms Campaign Setting places its base year at 1372 DR. Someone once told me that, at a point between this and the year of the current D&D 5e products, a sundering of the Spellweave killed off the wizards of Toril en masse.

Did any wizards survive this event, and do any wizards alive in 1372 DR survive to the “current” (D&D 5e) era?
